We have a PC with a genuine license for Windows XP Professional. Recently it started asking to be activated even though it had already been activated and has been working fine for the last couple of years.
After doing a format and install on more than one hard drive it asks for activation straight away, not giving the usual number of days to activate, and then after saying it is successfully activated asks you once again to activate. Then we are stuck in a loop of it saying please activate and "already activated" This has now happened to us on 3 Hard Drives.
Does anybody have any idea what we should try next to get the PC working properly?
